A Phase II Study About Efficacy and Safety of the Continuous IntraVenous Infusion of Ketamine as Adjuvant to Opioids in Terminally Ill Cancer Patients With Refractory Cancer Pain (CIVIK Trial).

Ketamine has been used to control refractory cancer pain as an adjuvant to opioids. We conducted a prospective phase II study to investigate the efficacy and safety of 5-day continuous intravenous infusion (CIVI) of Ketamine in terminally ill cancer patients with refractory cancer pain. Hospitalized terminally ill cancer patients with refractory cancer pain were enrolled. Refractory cancer pain was indicated by requirements for 4 or more rescue opioids or pain intensity using numerical rating scale > personalized pain goal (PPG) despite of intravenous morphine equivalent daily dose (IV MEDD) ≥ 120mg/day. The CIVI of ketamine was increased from .05mg/kg/hour to .5mg/kg/hour by .05 every 8 hours if pain intensity exceeded PPG or if number of rescue opioids ≥2 during prior 8 hours was required. The primary end-point was overall pain response rate, which indicates complete response (both rescue opioid ≤3/day and pain intensity ≤ PPG) plus partial response (rescue opioid ≤3/day), without unacceptable toxicities. Among 21 eligible patients enrolled between September 2019 and January 2023, 20 were analyzed. Most pain mechanisms were mixed type (n = 15, 75%), with neuropathic component (n = 17, 85%). The baseline background opioids were IV MEDD 186mg/24hour (range, 124-592), number of rescue opioids was 6 (IQR, 5-9), and median PPG was 4 (IQR, 3-4). The overall pain response rate was 50% (n = 10) including 40% (n = 8) for complete pain response and 10% (n = 2) for partial pain response. This study showed efficacy of gradually increasing CIVI of ketamine for terminally ill cancer patients with refractory cancer pain. CIVI of ketamine could be a useful tool in these patients considering the limited treatment options. (NCT03362073, Initial Release: November 15, 2017).

Evaluation of opioid prescribing for surgical patients discharged from three metropolitan hospitals between 2012 and 2020.

This multicentre, retrospective medical record audit evaluated opioid analgesia prescribing within a Victorian metropolitan public hospital network. The study included all surgical patients discharged between January 2012 and December 2020 with one or more discharge prescriptions from three metropolitan hospitals (n = 117,989). The main outcome measures were mean oral morphine equivalent daily dose (OMEDD), mean number of opioid types and proportion of patients prescribed one or more slow-release opioids on discharge.Total opioid prescribing (mean OMEDD) peaked in 2013. Between 2017 and 2020 there was a trend towards prescribing fewer opioids on discharge. Over the study period, there was decreasing prescription of codeine and increasing prescription of oxycodone and tapentadol. The proportion of patients prescribed slow-release opioids increased in the earlier years of the study, reaching a peak of 20.6% in 2017. Since 2017 there has been a rapid reduction in the prescription of slow-release opioids.Subanalysis was undertaken to evaluate key changes in the opioid prescribing landscape in the health network. The removal of default opioid pack sizes in the electronic medication management system (December 2014) and the release of the Faculty of Pain Medicine-Australian and New Zealand College of Anaesthetists' statement regarding the use of opioid analgesics in patients with chronic non-cancer pain (March 2018) were associated with significant reductions in mean OMEDD prescribed on discharge (136 mg vs 122 mg and 120 mg vs 85.4 mg, respectively, P < 0.001).In conclusion, the quantity of opioids prescribed on discharge in this patient group peaked in 2013 and has been decreasing since.

Clinical prediction of opioid use disorder in chronic pain patients: a cohort-retrospective study with a pharmacogenetic approach.

Opioids are widely used in chronic non-cancer pain (CNCP) management. However, they remain controversial due to serious risk of causing opioid use disorder (OUD). Our main aim was to develop a predictive model for future clinical translation that include pharmacogenetic markers. An observational study was conducted in 806 pre-screened Spanish CNCP patients, under long-term use of opioids, to compare cases (with OUD, N.=137) with controls (without OUD, N.=669). Mu-opioid receptor 1 (OPRM1, A118G, rs1799971) and catechol-O-methyltransferase (COMT, G472A, rs4680) genetic variants plus cytochrome P450 2D6 (CYP2D6) liver enzyme phenotypes were analyzed. Socio-demographic, clinical and pharmacological outcomes were also registered. A logistic regression model was performed. The model performance and diagnostic accuracy were calculated. OPRM1-AA genotype and CYP2D6 poor and ultrarapid metabolizers together with three other potential predictors: 1) age; 2) work disability; 3) oral morphine equivalent daily dose (MEDD), were selected with a satisfactory diagnostic accuracy (sensitivity: 0.82 and specificity: 0.85), goodness of fit (P=0.87) and discrimination (0.89). Cases were ten-year younger with lower incomes, more sleep disturbances, benzodiazepines use, and history of substance use disorder in front of controls. Functional polymorphisms related to OPRM1 variant and CYP2D6 phenotypes may predict a higher OUD risk. Established risk factors such as young age, elevated MEDD and lower incomes were identified. A predictive model is expected to be implemented in clinical setting among CNCP patients under long-term opioids use.

Cultivating optimal analgesic prescribing practices in a metropolitan hospital network: evaluating an analgesic stewardship program

AbstractBackgroundThe increasing incidence of opioid‐related harm associated with inappropriate opioid prescription underscores the need for effective interventions directed at enhancing analgesic prescribing practices. Analgesic stewardship (AGS) programs have emerged to facilitate appropriate analgesic use, reducing analgesic‐related harm and optimising patient outcomes.AimThis study aimed to assess the impact of an AGS program on the appropriateness of opioid analgesia prescribing for adult inpatients within a metropolitan health network during the initial two months following program implementation.MethodThis retrospective audit examined de‐identified aggregate data of 100 adult inpatients of a major Australian metropolitan hospital network between August–September 2022. The multidisciplinary AGS program involving pharmacy, nursing, and medical staff provided clinical interventions and recommendations for patients, supported by organisational interventions, including education and guideline reinforcement. Data collection included patient demographics, clinical data, and AGS program recommendations documented in patient medical records. Ethical approval was granted by the Eastern Health Office of Research and Ethics (Reference no: QA23‐015‐91886) and the study confirms to the Australian Statement on Ethical Conduct in Human Research.ResultsIt was found that 51% of opioid‐naïve patients were prescribed modified‐release opioids for acute non‐cancer pain, contrary to local guidelines. The AGS program recommendations resulted in an 89.7% cessation of these prescriptions. For non‐opioid‐naïve patients, there was a statistically significant reduction in mean Oral Morphine Equivalent Daily Dose of 19.85 mg (95% confidence interval [CI] 10.3–29.4 mg, p &lt; 0.05). AGS recommendations were predominantly adhered to, with 82% showing full or partial compliance.ConclusionThis study highlights the positive impact of an AGS program on the appropriateness of opioid analgesic prescribing for adult inpatients. These findings support the implementation of AGS programs into healthcare systems to mitigate opioid‐related harm and improve patient outcomes.

Characteristics and outcomes of peripheral neuropathic pain patients with repeated applications of high-concentration capsaicin cutaneous patch: Results of a retrospective chart review in Germany.

The aim of this study was to evaluate patient characteristics, concomitant analgesic medication, and pain intensity in a real-world setting in Germany, focusing on the repeated application of high-concentration capsaicin patch (HCCP) for neuropathic pain. Data were collected from electronic medical records of patients who received at least two HCCP treatments between January 2011 and July 2022. Subgroup analyses were performed based on the number of HCCP treatments, age groups, and specific neuropathic pain conditions. The study was conducted at an outpatient pain center in Wiesbaden, Germany. The study included 97 patients, primarily diagnosed with neuropathic back pain, postoperative or post-traumatic neuropathic pain, and postherpetic neuralgia. The daily dose of concomitant medications (eg, opioids and anticonvulsants) at the start of capsaicin therapy was compared with the average within 2 years of capsaicin therapy. The last observation carried forward method was used if HCCP treatment was discontinued before the end of the 2-year period. The majority of patients received concomitant medications, with opioids, anticonvulsants, and antidepressants being the most common. The average daily morphine equivalent dose decreased significantly during HCCP treatment. Pain intensity at baseline was generally high, but substantial improvements were observed in patients who received at least three HCCP applications. This study provides evidence for the effectiveness of HCCP treatment in reducing pain intensity and concomitant opioid use in patients with neuropathic pain. Further research is needed to explore the long-term outcomes and optimal treatment regimens for different patient populations.

The potential role of social support in reducing risk of opioid misuse following traumatic injury

Background Social support appears to play a pivotal role in the prevention, development, and remission of substance use disorders. Previous research suggests that interpersonal relationships moderate treatment outcomes for opioid use disorder based on the nature and quality of the relationship. However, the role of social support in the initiation of prescription opioid misuse (POM) is unclear. Methods In a prospective cohort of 221 patients with traumatic injuries at a level 1 trauma center in Wisconsin, we used multiple linear regression analysis to examine the association between social support and POM at six months post-discharge. Covariates included morphine equivalent daily dose (MEDD) at baseline (24 h pre-discharge), opioid use at six months post-discharge, pre-injury depression and anxiety symptoms, and discharge pain intensity. Results In models adjusted for relevant demographic and clinical outcomes, social support scores (β = −3.898, p < 0.001; Bonferroni corrected) and depression and anxiety composite scores (β = 2.29, p < 0.023; uncorrected) significantly predict POM scores 6 months post-discharge. When controlling for pre-injury depression and anxiety, patients with positive POM scores had significantly lower baseline social support scores than patients with negative POM (M = 24.31 vs 30.05, p = 0.003). Conclusions Findings suggest that the perceived presence and quality of social support within an individual’s life may influence the initiation of POM and should be considered in screening for risks related to potential POM. Providers may consider the use of social support when stratifying patients for risk of possible misuse.

Real-world experience of patients with sickle cell disease treated with crizanlizumab.

In 2019, crizanlizumab was approved by the Food and Drug Administration (FDA) to reduce the rate of vaso-occlusive crisis in patients with sickle cell disease (SCD). We aimed to study the real-world effectiveness of crizanlizumab in our comprehensive sickle cell center. This was a retrospective cohort analysis of patients with SCD who received at least two consecutive doses of crizanlizumab. Clinically significant improvement was captured using the patient global impression of change scale (PGI-C). As of December 2022, there were 18 patients eligible for analysis with a median age of 30.5 years. Eight patients had the HbSS genotype, 7 HbSC, and 3 HbSB null genotype. Median duration of exposure to crizanlizumab was 53.6 weeks, and 16 (88.9%) patients received crizanlizumab for ≥26 weeks. Crizanlizumab was very well tolerated with no serious adverse events (grade ≥3) related to treatment. There was no significant difference in laboratory parameters. There was a remarkable improvement in patients' subjective response to crizanlizumab infusion. The median PGI-C score of our patients was 5, signifying moderately better with slight but noticeable changes. The morphine equivalent daily doses (MEDD) were lower after crizanlizumab infusion. MEDD prior to crizanlizumab was 90; after ≥2 consecutive crizanlizumab doses, it was 60. There was also a reduction in the hospital admissions, emergency, and urgent care visit for acute pain crisis in 6 (28%) patients. This study shows that crizanlizumab was associated with improvement in patients' response, both directly and indirectly related to the reduction of opioids used, which is consistent with results from the SUSTAIN trial.

The Impact of a Clinical Pharmacist Practitioner on Perioperative Pain Management for Orthopedic Surgeries

The objective of this quality improvement (QI) project was to assess the impact of an evidence based clinical pharmacist practitioner (CPP) model applied to perioperative pain management by integrating a CPP into the perioperative orthopedic surgery clinical pathway. Secondary objective was to assess the effect of CPP pain management service on surgical team satisfaction. This QI project expanded CPP pain management services for patients who were scheduled for an orthopedic surgery. Surgical provider satisfaction of CPP pain management services was assessed through a provider survey. Pain management recommendations by the Pain CPP were implemented 61% (n = 23/38) of the time by the orthopedic surgeon. The impact of the Pain CPP on perioperative pain management was demonstrated by improvement in the Clinically Aligned Pain Assessment Tool, which was similar in patients where CPP recommendations were accepted compared to surgeon only recommended regimens (p = 0.048). Five orthopedic surgical providers responded to our satisfaction survey, 80% (n = 4/5) strongly agree that a pain management CPP should become a permanent member of the care team. Through an evidence-based CPP model we observed a reduction in quantity of opioid prescribed and morphine equivalent daily dose utilized in patients who underwent an orthopedic surgery.

COVID-19 and End of Life in a Quaternary Australian Hospital: Referral for Palliative Care Consultation.

The coronavirus disease 2019 (COVID-19) pandemic resulted in complex physical and psychosocial symptom burden at end of life. The benefit of specialist palliative care input in other disease states has been established, however, there is little evidence on referral patterns to these services in patients dying from COVID-19. This retrospective audit investigated the referral patterns for patients who died from COVID-19 at a quaternary hospital in South Australia (the Royal Adelaide Hospital) over a six-month period in 2022, and whether demographic features or COVID-19 specific factors had an impact on whether these patients received specialist palliative care services (PCS). The second aim was to identify prescription patterns for patients in the last 24 hours of life, and whether this was impacted by referral. Data were obtained from electronic medical records and analyzed using binary logistic regressions for referral to PCS versus no referral based on various predictors. There was no significant difference comparing patient demographics or COVID-19 specific factors with referral to PCS. There was statistical significance between patients who received referral to PCS and those who had a higher oral morphine equivalent daily dose (OMEDD) in the 24 hours before death, as well as the presence of a continuous subcutaneous infusion. Although the cause of this relationship is undetermined, it may represent the prescription patterns of the palliative care physicians during consultation or potentially higher symptom burden prompting referral. There was also a higher proportion of patients who received hydromorphone compared with other opioids, though the OMEDD was consistent with other published literature.

Opioid-Related Respiratory Depression in Non-Cancer Patients, as Reported in the Japanese Adverse Drug Event Report Database.

Opioid-induced respiratory depression (RD) is a potentially life-threatening adverse drug event. This study used the Japanese Adverse Drug Event Report (JADER) database to investigate the profile of opioid-related RD in non-cancer patients. We analyzed data recorded in the JADER database between April 2004 and February 2020, which were downloaded from the Pharmaceutical and Medical Devices Agency website. Reporting odds ratios for RD were calculated for the 20 opioids approved in Japan, and daily dose and onset time were further analyzed for opioids used in chronic non-cancer pain (CNCP). Among the opioids, RD adverse event signals were detected for 22 combinations of opioids and administration routes in non-cancer patients. Of these combinations, transdermal buprenorphine and oral tramadol/acetaminophen were approved for CNCP and tended to be reported more frequently in elderly patients. The median daily doses of transdermal buprenorphine and oral tramadol/acetaminophen were 10.0 and 22.5 mg of daily oral morphine equivalent doses, respectively, which are within the standard range for starting dosage. The median time-to-onset of transdermal buprenorphine and oral tramadol/acetaminophen was 6.5 and 4.0 days, respectively, and 75% of cases were reported within 20 to 40 days after the start of treatment. The hazard type for both opioids was classified as early failure. Our findings suggest that elderly CNCP patients should be closely monitored after the start of opioid treatment, especially during the first week and, if possible, for 1 month, even if starting doses are within ranges recommended by the manufacturer and guidelines.

Outpatient cross-titration to buprenorphine for chronic pain: A retrospective analysis.

To determine the effectiveness and safety of the University of Washington's buprenorphine cross-titration protocol for chronic pain in the outpatient setting. Retrospective chart review was performed on 150 patients transitioned from full µ-opioid agonist therapy to buprenorphine using the University of Washington Medical Center Pain Clinic's cross-titration protocol between September 1, 2020, and December 31, 2021, in an outpatient setting. Primary outcome was to determine the percentage of patients who completed the cross-titration and continued buprenorphine without full µ-opioid agonists 4 weeks after completion. Secondary outcomes included final buprenorphine dose, days needed to complete cross-titration, deviation rates from the protocol, and opioid-related adverse events. Fifteen of 31 (48.4 percent) included patients successfully converted to buprenorphine. Median duration of successful cross-titration was 29 days (interquartile range 19-57). Average end-titration dose for patients on buprenorphine/naloxone sublingual films was 7.9 ± 5.7 mg/day, while for buprenorphine transdermal (TD) patches, it was 11.9 ± 4.8 mcg/h. Morphine equivalent daily dose (MEDD) prior to induction varied widely. All patients transitioned to TD buprenorphine were taking ≤30 mg MEDD. Patients previously taking >120 mg MEDD stabilized on 8-16 mg/day buprenorphine. Most common reasons for cross-titration failure were inadequate pain control and intolerable adverse effects. The University of Washington's buprenorphine cross-titration protocol for chronic pain was successful in about half of included patients undergoing conversion from chronic full µ-opioid agonist therapy and generally well tolerated. Clinical responses were widely variable, and many required slower taper and higher end-titration buprenorphine dose than anticipated. Although protocols provide structure for cross-titration, each course should be monitored closely and individualized.

Transcutaneous electrical acupoint stimulation for cancer-related pain management in patients receiving chronic opioid therapy: a randomized clinical trial.

The opioid crisis resulting from its use disorder and overdose poses additional challenges for cancer pain management. The American Society of Clinical Oncology Practice Guideline recommends acupuncture therapy for the management of adult cancer-related pain (CRP), but the effectiveness of transcutaneous electrical acupoint stimulation (TEAS) on CRP remains uncertain. This 5-week prospective randomized clinical trial was conducted at 2 hospitals in China, and participants with CRP receiving chronic opioid therapy were randomized 1:1 into two groups between December 2014 and June 2018. The true TEAS group underwent 15 sessions of TEAS treatments over 3 consecutive weeks, while the control group received sham stimulation. The primary outcome was the numerical rating scale (NRS) score in the past 24h at week 3. The secondary outcomes included morphine equivalent daily dose, quality of life and adverse events. A total of 159 participants were included in the modified intention-to-treat population. The baseline characteristics were similar in both groups. The mean NRS scores were 0.98 points at week 3 in the true TEAS group and 1.41 points in the sham group, with the mean difference between groups of -0.43 points (P < 0.001; OR = 0.68, P < 0.05). The proportion of patients with NRS reduction more than thirty percentage at week 3 was 50.00% in the true TEAS group and 35.44% in the sham group (RD = 0.15, P > 0.05; RR = 1.41, P > 0.05). No significant difference in pain intensity between the two groups was observed during the follow-up period without TEAS intervention (week 4, OR = 0.83, P > 0.05; week 5, OR = 0.83, P > 0.05). The Karnofsky Performance Status value suggested that patients in the true TEAS group experienced an improved quality of life (Between-group differences: week 3, 3.5%, P < 0.05; week 4, 4.6%, P < 0.001; week 5, 5.6%, P < 0.001). The 3-week application of TEAS in patients with CRP receiving chronic opioid therapy resulted in a statistically significant reduction in pain scores, but the observed reduction was of uncertain clinical significance. The prolonged analgesic effect of TEAS was not confirmed in this trial. GOV: ChiCTR-TRC-13003803.

The Impact of Enhanced Recovery After Surgery Protocol Implementation on Postoperative Pain Management in the Era of Opioid Crisis: The Post- Chemotherapy Open RPLND Experience.

Enhanced Recovery After Surgery (ERAS) protocols have been proven to optimize postoperative outcomes; however, misuse of opioid analgesics can still hinder postoperative recovery due to related side effects and potential complications. To determine if the implementation of ERAS protocol in post-chemotherapy retroperitoneal lymph node dissection (PC-RPLND) patients could help with reducing postoperative pain and opioid use. A case-control study of consecutive testicular cancer patients with indications for PCRLPND, who were offered Conventional Post-operative Management (CPM) or ERAS protocol. Outcomes of interest included Visual Analogue Scale (VAS)-assessed pain level at postoperative days 3, 7, and 30, and Morphine-Equivalent Doses (MEDs)/postoperative day. Intraoperative parameters and postoperative complications were recorded. Parametric and non-parametric tests were used for statistical analysis. In total, 100 opioid-naïve PC-RPLND patients were studied. CPM and ERAS groups (36 and 64 patients, respectively) had similar demographic and baseline clinical characteristics). ERAS group patients had significantly lower blood loss (p = 0.005), blood transfusion rate (p < 0.001), and duration of the procedure (p < 0.001). Post-operative complications were comparable between groups. Nausea and bowel disorders were numerically but not statistically more frequent in the CPM group. ERAS patients had shorter mean hospital stay (5.3 ± 1.4 vs. 7.4 ± 1.6 days, p < 0.001), lower daily MEDs (4.73 ± 2.63 vs. 7.04 ± 2.29, p < 0.001), and lower VAS scores on post-operative day 7 (3.89 ± 1.07 vs. 4.67 ± 1.17, p = 0.001). Post-operative pain was similar between groups on post-operative days 3 and 30. Systematic implementation of ERAS protocol after PC-RPLND improves pain management, optimizes patient recovery, and prevents over-prescription of opioid analgesics.

Sickle Cell Disease and Comorbid Psychiatric Conditions: A Single-Center Retrospective Study

Introduction: It is established that patients with various chronic disease states are predisposed to psychiatric comorbidities. However, in the sickle cell disease (SCD) patient population, psychiatric comorbidities have been uniquely shown to exacerbate disease through a psychosomatic component. A co-existing diagnosis of depression is found in 1 of 3 patients with SCD, and they are more than 5 times as likely to suffer from a mood disorder than the general population. SCD patients with psychiatric illnesses have significantly worse physical and mental health outcomes. Additionally, healthcare costs are more than double for SCD patients with depression than for those without. Thus, SCD patients with psychiatric comorbidities have unique challenges and are an important population to study. Methods: This was a retrospective single-center study of patients with SCD, all genotyped and ≥16 years old, who were treated at UT Physicians Comprehensive Sickle Cell Center during the study period (March-July 2023). The demographics, clinical characteristics, psychiatry history, initial and recent PHQ-9 results, and laboratory findings were collected and analyzed. Descriptive statistics were obtained and analyzed between SCD patients with and without psychiatric disorders and are presented in percentages, medians, and interquartile ranges. Data analysis was completed using a p value &amp;lt; 0.05 to indicate statistical significance, using an independent group unpaired t-test for continuous variables and Chi-square and Fisher's exact tests for categorical data, respectively. Data was analyzed using GraphPad Prism version 9.0.2. Results: Patient sex was 45% male and 55% female; 73% of patients had the HbSS genotype. Of the studied cohort, 33% were affected by at least one psychiatric disorder. The most common psychiatric disorder was depression, which occurred in 26% of patients, followed by anxiety (21%). The most common pharmacotherapy for psychiatric conditions was tricyclic antidepressants (TCAs), followed by SSRIs and SNRIs. There was no significant difference in ED visits or hospitalization rates between patients with known psychiatric disorders versus those without. Common laboratory markers used to assess SCD (LDH, total bilirubin, reticulocyte count) were overall higher in the subset with psychiatric illnesses, but only LDH was statistically significantly higher. Surprisingly, SCD patients with psychiatric disorders used fewer opioids than those without with a lower Morphine Equivalent Daily Dose (although this was not statistically significant). Conclusion: Although it is known that psychiatric illnesses in SCD patients are prevalent, exacerbate disease, and pose a cost burden, in our study there was nosignificant increase in hospitalizations or ED visits. However, it is notable that our study patient population was an outpatient population that is compliant and generally has access to resources including a robust behavioral health team and regular psychotherapy sessions. Due to these factors, ourdata may not be generalizable to the entire SCD patient population. Additionally, althoughlaboratorymarkers were overall poorer in the psychiatric population, they were not statistically significant, perhaps owing to the small sample size. Our study calls for a broader look at SCD patients with psychiatric illness, perhaps also to review these variables in SCD patients in the inpatient setting. A future direction could also be to evaluate the efficacy of psychiatric pharmacotherapy versus cognitive behavioral therapy in this patient population. Word count: 518 words

Comparison of different sustained-release opioids and acute respiratory conditions in patients with cancer and chronic kidney disease.

Few data are available on the association between the use of oxycodone in patients with chronic kidney disease (CKD) and acute respiratory conditions. The aim of this study was to investigate whether oxycodone is associated with an increased risk of acute respiratory conditions in patients with cancer and CKD compared with other opioids. The data were obtained from a claims database in Japan. Patients with cancer and CKD who had received sustained-release opioids, including oral oxycodone, oral morphine, or transdermal fentanyl, between April 2014 and May 2021 were selected. The primary outcome was defined as an acute respiratory condition. Data for age and sex, morphine equivalent daily dose, concomitant use of specified medications, comorbidities defined based on the modified Charlson comorbidity index, substance use disorder, and lung cancer or metastatic lung cancer were investigated as covariates. Distribution of acute respiratory conditions was compared among the three sustained-release opioid groups using the log-rank test. Estimates of the incidence of acute respiratory conditions were compared among the groups using a Cox proportional hazards model with time-varying variables. A significant difference in the distribution of acute respiratory conditions was found among the three groups (p < 0.01). Cox regression analysis showed a significantly higher risk of acute respiratory conditions with morphine (hazard ratio [HR]: 3.04, 95% confidence interval [CI]: 1.07-8.65, p = 0.04) compared with oxycodone but no significant difference in risk with oxycodone (HR 0.67, 95% CI: 0.32-1.38, p = 0.27) compared with fentanyl. The findings suggest that the risk of acute respiratory conditions may be lower in patients with CKD who use oxycodone for cancer pain than in those who use morphine. Additionally, no difference in the risk of acute respiratory conditions was found between oxycodone and fentanyl use.

Opioid dose risk, clinician and patient characteristics, and adherence to opioid prescribing recommendations in chronic non-cancer pain.

This study aims to assess associations between morphine-equivalent daily dose (MEDD) of opioids, clinician and patient characteristics, and prescriber adherence to guidelines for long-term opioid therapy (LTOT) in chronic noncancer pain (CNCP) and to elucidate potential relationships associated with increased-risk opioid prescribing. Retrospective cross-sectional study. Academic health system's 33 primary care clinics. Adults (≥18 years old) prescribed LTOT (10 + outpatient prescriptions in the past year) for CNCP. Electronic health record data on prescribed opioids (for MEDD), clinician/patient characteristics, and adherence rates to LTOT guideline-concordant recommendations. A total of 2,738 patients were eligible, 61.6 percent Lower, 15.7 percent Moderate, and 22.7 percent Higher Risk MEDD (<50, 50-89, and ≥90 mg/day, respectively). Higher MEDD correlated (p < 0.001) with Medicare insurance, current cigarette smoking, higher pain intensity and interference scores, and the presence of opioid use disorder diagnoses. Male clinicians more frequently prescribed (p < 0.001) and male patients were more likely to be prescribed (p < 0.001) higher MEDD compared to their female counterparts. Higher Risk MEDD was associated with higher coprescribed benzodiazepines (p = 0.015), lower depression screening (p = 0.048), urine drug testing (p = 0.003), comparable active treatment agreement (p = 0.189), opioid misuse risk screening (p = 0.619), and prescription drug monitoring checks (p = 0.203). This study documented that higher MEDD was associated with risks of worse health outcomes without improved adherence to opioid prescribing guideline recommendations. Enhanced clinician awareness of factors associated with MEDD has the potential to mitigate LTOT risks and improve overall patient care.

Shifting quality chronic pain treatment measures from processes to outcomes.

Misapplication of the 2016 Centers for Disease Control (CDC) opioid prescribing guidelines has led to overem-phasis of morphineequivalent daily dose (MEDD) as a "metric of success" in chronic noncancer pain (CNCP), resulting in unintentional harms to patients. This article reviews CNCP-related guidelines and patient preferences in order to identify pragmatic, patient-centered metrics to assess treatment response and safety in opioid-treated CNCP. We reviewed the clinical (CDC), research (Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials), and implementability-related guidelines (GuideLine Implementability Appraisal), along with relevant patient-identified treatment goals. From these, we summarize a guideline-concordant, patient-centered, implementable set of measures to aid the clinical management of opioid-treated CNCP. We identify metrics across three domains of care: (1) treatment response metrics, which align with the CNCP care goals (pain intensity, pain interference including function and quality of life, and global impression of change); (2) risk assessment ("safety") metrics, eg, MEDD, benzodiazepine-opioid or naloxone-opioid coprescribing, and severity of mental health disorders, which evaluate the risk-benefit profile of opioid therapy; and (3) adherence ("process") metrics, which assess clinician/patient adherence to the guideline-recommended opioid therapy monitoring practices, eg, the presence of completed treatment agreement or urine toxicology testing. All metrics should be informed by implementability principles, eg, be decidable, executable, and measurable. This article summarizes guideline-concordant, patient-centered, implementable metrics for assessing treatment response, safety, and adherence in opioid-treated CNCP. Regardless of which specific treatment guidelines are applied, this approach could help conceptualize and standardize the collection and reporting of CNCP-relevant metrics, compare them across health systems, and optimize care and treatment outcomes in opioid-treated CNCP.
